Application tiled January 21, 1913. Serial No. 743,324`

To rho-m t may concer-n,

Be 1t known that l, lili-mai' MILLS, a citizen of the United b tates,residing in .Philadelphia, Pennsylvania, have invented certainimprovements in liim Construction, oi which the following isasl'iecifieat-ion.

One ob jeet of my invention is to provide a rela'tivel)v simple devicefor retaining any structure on the telly or rim of a wheel, of suchConstruction that it may be removed or replaced with the greatestease inorder to permit of the convenient removal or replacing of the member orpart which it ordinarily holds-in place.

Another object of the invention is to provide a. wheel with a retainingring of novel construction, in combination with adjustable holdingmeans, such as bolts, so arranged that ait'ter said bolts have beenloosened or the outward pressure has been ren'ioveftl from-said ring,the .latter may be brought into a. removable, position byrotatiirfthrough a. relatively small angle, and thereafter be lifted oitof the holding means by beingfdrawn outwardly from the wheel.

These objects I attain as hereinafter set lforth, reference,beingv hadto the aecompanying drawings, in which, Figure l is a side elevation ofa wheel equipped witlrmy invention; Fig. 2 is an enlarged transversesection of a portion of the wheel shown in Fig. l; Figs. 3 and -l are`transverse sections showing slightly modified forms o't' my invention,and Fig. is a fragmentary side elevation 'of that form of retaining-ring shown in Figs. Zand 3.

In'thef above drawings, i' represents the hub and the rim of a wheel, onthe latter of which is mounted any desired form ot' tire, consisting, inthe ease shown in Fig. 2, of a shoe 3 and an inner tube el. In thisparticular ease, one edge of the rim is pro vided with an upwardlyextending ange 5 by which the tire retaining' ring G is held in placeVin the well known n'ian'ner. In the present instance, the said rim isprovided with an;7 suitable number o1" lugs '7 projecting inwardlyvvfrom its inner surface and 'having threaded openings adjacent the unflanged edge of the rim for the reception of For engaging and holdingthat side of the tireshoe adjacentthe uotlangz'ed edge of the. rim. l,provide a rinej il whose outer edge, like. that et' the ring 6. isoutwardly curved or ilared and has a series ot' open .outwardly overthem.

sided recesses l0 for the reception of: the bolts 8. so arrangedthat therotation of the ring 8 through a small are about thecenter oi" thewheel,will cause said bolts to be .brought into these recesses orl permit thering to beA ireed from said bolts, as the ease ma)-Y be. Moieover,ftlieinternal diam` eter of the ring 9 is such'or said ring is so .formedthatI when the bolts are altogether free oi their respective recesses,it will just Clear their heads and mav be completelY removed from thewheel y being drawn It will further be noted that eoneentrie with eaehof then-eeesses l0,`the outer face of the ring t) is comiteusunli asindieiated at 1l for the reception of the bolt heads, the arrangementbeing such that when the latter lie within the counter-sunk recesses, itis not possible for the ring` to be. rotated.,

lnder conditions of use, if it be desired to lremove the tire Il l .fromthe rim 2, it -is onliv necessary that the parts restingr on the rimbel-)ushed towardeaeh other, or if desired, that the bolts be partialhrunserewed, whereupon it is possible to give'-the'rirr;r 9 a rotationthrtmg'h a small angle in the direction otthearrow Fig. Itm'aybethenfreed from the bolts S, it being of course necessary .that it bepushed inwardlg7 toward the rim before'it is turned in order to free theheads of the bolts from the sides of t-he countersunk recesses l1, inease the bottom portions oi the shoe 3 are movedtoward each otherinstead oi part-iall)7 unseren-ing the bolts. Obviously, the ring ma;Ynow be drawn outwardlvy over the heads of the bolts Svwhioh, as beforenoted, are at such a distance-troni theeenter of the wheel as to permitof this action. The tire may now be easily removed from the rim withoutloss ot time, and when it is desired to reassemble the various parts.

said tire is again placed upon the rim and after the ringl 9 has beenput in place over the heads of the bolts-S. it is turned in a directionthe reverse of that indicated by the.

arrow in Fig'. until said bolts are fully entered in their respectiverecesses. The latter muv now be screwed up until, their heads enter thecountersunk recesses 1l. or it the ,bolts are aire-advY set up to thedesired point, the tire may." be mii-ated so as to eauw.` the properfunctioning" of the parts'.

ln Fie". 3 l have shown a slightly motufled t'orrn ot as v ravention inwhleh the wheel is arm ded with a wooden tell f l2 havinf-Y me .e l l?llO structures,

tallic Vsockets 13 set therein and provided with threaded holes for 'thebolts 8t In this instan,.hpwever, 4the tire 3 4 1s of the clencher typeso Vthat the ring` 6 has its outer j curvedinwardly as has also theremov- 'ah This as before, is counter mi 'Iqtthe rece tion of the boltheads 8 i1!- tlius lield, om accidental movement llvtiv'el'y tothe boltsafter `these have 'been ipp u nder working conditions y .is obviousthattheinvention is by no confined to use in connection with rims and tiresof the'construction shown in the above' described drawings, ysince itmay b e'used whenever it is desired to removably retain' any structureofa. similar nature in place on the elly or rim of awheel. For exam le, in'Fi 4 I have shown a portion of a emountab e rim structure in which theremovablering 9* is provided with anyy suitable number of the inwardlyextending wedges 14 'whereby the body 15 of the rim is roperly held inplaee on the felly 12". As fore, this ring 9" is employed ln-oonnectionwith 'a seriesof bolts or other suitable screwed into or attached' tothe fell or other Wheel part mounted on the 'spo es 1 and has recessesopen at one side to permit of its en gement with orv disengagement fromsaiaholding structures by 'a slghtrotary movement ;-the internaldiameter of the ring being locally or wholly such that when the holdingstructures are clear' of its recesses, it may be drawn o over theirheads.-

.From the above it will be seen that my improved holding or retainingring is applicable not only to keep a. tire on a rim but also to hold aremovable or other similar rim 4e on a wheel.

I claim n 1. The combination in a wheel of a. member removably mountedthereon; and holding means for said'member consisting of a series ofbolts adjustably threaded into the wheel; with a flat retaining ringprovided with inwardly projecting portions havin Epen sided recesses forthe reception of sai lts.

2. The combination in a wheel of a rim having a series of threadedsockets; a tire mounted' on said rim; means for holding the tire inplace consisting of a ring provided with a series of open sidedrecesses; and bolts mounted in the sockets. in positions to enter therecesses of the ring, the latter being removable from the bolts by arotary movement and theonter face of the ring being conntersunk adjacentthe recesses to Egevent such rotary movement when the lts are not setup.

3. The combination in a Wheel of a rim having a series of threadedsockets a tire mounted on said rim; means for holding the tire in placeconsisting of a ringr having n dat rtion in a plane at, right angles tothe axis of the Wheel and provided at its -inner edge with inwardlyprojecting portions formed with open sided recesses, the

outer face of said ring bein 'counter-sunk around and recesses; with bots mounted in the sockets in positions to enter the recesses of the ringthrough the openings thereof.

Intestimony whereof, I have signed my name to' this specification, inthe presence of two subscribing witnesses.
